Replying to Concussion/ PCS with no direct impact?

So In January I hit my head got stars and a stiff neck basically knew right away something was up , got diagnosed with my 2nd concussion the day after, waited a few weeks resting or whatever and then got right back to skiing once my doctor cleared me to return to normal activities.

Fast forward to this past Sunday, I bailed pretty on my hip hard a few times, but didn't hit my head once. Felt completely fine besides a really sore hip leaving the hill, woke up Monday morning completley feeling fine, went to school whatever felt great until about 10pm monday night started to feel a bit off.

Past tuesday and today I've been feeling pretty out of it and having minor headaches.

I booked an appointment with a sports physician to make sure, but
was wondering if anyone here on NS has had any experience with having concussion symptoms multiple days after a crash/ concussion symptoms without even hitting your head?
